"Adeno-Associated Virus Vectors Transduce Primary Cells Much Less Efficiently than Immortalized Cells."

According to the authors' abstract of an article published in Journal of Virology, "Immortalized cell lines have been used to study infection and replication of adeno-associated virus (AAV) in culture, but primary cells presumably provide a better model for AAV behavior in animals. Here, we have evaluated the ability of AAV vectors to transduce primary and immortalized strains of human epithelial cells and fibroblasts. Two AAV vectors were used, one that transduced an alkaline phosphatase gene (AAV-LAPSN), and one that transduced a beta-galactosidase/neomycin phosphotransferase fusion gene (AAV-L beta geo). The transduction efficiency of the AAV-LAPSN vector, quantitated by measurement...
